る。Since the shaft bearing has bearings, preferably tapered roller bearings, arranged on both sides of the cylinder block,
A wider bearing base is obtained, which can accommodate large lateral forces. The cylinder block is supported radially on the drive shaft. However, it is also possible to mount the cylinder block on the outside. In this outer bearing, torque is introduced into the drive shaft or pinion shaft without lateral forces. In any case, the torque generation takes place in the pivot drive according to the invention in the axial direction between the bearings of the shaft bearing or the pinion bearing.
